Q: How to replace the Differential Seal in the drive pinion housing on Chevrolet Silverado 1500?
A: The process of drive pinion housing or seal replacement requires initial observation of all driveline component positions relative to propeller shafts and axles before disassembly according to their original locations following specifications with torques values. The first step involves vehicle lifting followed by draining all lubricant from the axle bearing system. The drive proceeds by unattaching both rear axle shafts together with the rear propeller shaft based on whether the design uses one piece or two pieces. To take out both the drive pinion flange or yoke and oil seal you need a hydraulic press and matching equipment. The collapsible spacer needs removal before using a hammer and brass drift to gently extract both pinion bearing cups in equal steps. The installation process requires the j 37624 (Pinion Bearing Installer) and j 8092 (Universal Driver Handle) to place the inner pinion bearing cup and then install the outer pinion bearing cup by using the j 8608 (Pinion Bearing Cup Installer) and j 8092 (Universal Driver Handle). Sealant should be applied to the selective shim before installing the pinion gear bearing retainer along with its bolts that need to be tightened to 88 nm (65 lb ft). Allow the drive pinion flange/yoke or oil seal to reenter its place followed by the propeller shaft before completing the installation with the rear axle shafts. To finish up the procedure you need to add lubricant to the axle before taking away the support to lower the vehicle.
